Not exactly. There was talk about that early on. You can not use the sensor
port to drive a motor, and you can not use the motor port to read an analog (old
style) sensor.
The hardware specs may have changed, so I may not be 100% on this, but I think
the hardware will allow you to connect a digital sensor to any of the seven
ports. However, the NXT software (currently) doesn't allow you to configure the
motors ports as another type of sensor. (only as a built-in rotation sensor).
So, in addition to the four digital lines in each port, there are two lines that
represent input and output, as we know it from the RCX. (I think)
